Even though this guy used 1000W worth of CFL's in a closet with 2 5 gallon buckets from seed. He mentioned that it takes 5 weeks for a vegetating plant to reach maturity and you can tell when the plant stops developing 2 leafs opposing nodes and start alternating with one leaf. He also topped each plant twice during the veg stage and has great pictures along the way.
i use the 10in pots, just my opinion but im not impressed i got them with the thought that the bigger pot would stabilize the plant in later flower ..yeah bs lol. and the root ball for each of my plants takes up about 3gallons of space in 4 gallons of nute mix. peeaaccce
